Ethylene-Vinyl Acetate (EVA) is a Commodity Polymer that is a copolymer of Ethylene and Vinyl Acetate. EVA copolymer is classified into three categories according to Vinyl Acetate content present. The first type is EVA containing low VA percentage. This category of Ethylene-Vinyl Acetate is used as a Thermoplastics Material. The second type of EVA consists of 4% to 30% of VA and it is used as a Thermoplastic Ethylene-Vinyl Acetate. The third category of Ethylene-Vinyl Acetate consists of more than 40% VA and it is used as Ethylene-Vinyl Acetate Rubber. The process of manufacturing Ethylene-Vinyl Acetate involves a method wherein Ethylene and Vinyl Acetate are continuously polymerised. This continuous polymerisation is performed in a Polymerising Vessel.
